The Delta variant of COVID-19 is the dominant strain in the US and is more contagious and easily transmissible than previous strains. It is infecting more people than ever before and changing the guidelines for staying safe during the pandemic. Vaccination is the best protection against the Delta variant. Studies suggest that the currently authorised vaccines work on the Delta variant and are highly effective in preventing severe illness, hospitalisation, and death. However, vaccinated individuals can still spread the virus and may need to take precautions such as wearing masks and social distancing.

Vaccines are highly effective against the Delta variant
Vaccines are highly effective in preventing serious illness and death from the Delta variant. Research from the UK suggests that the Pfizer vaccine is 88% effective at preventing symptomatic infections caused by the Delta variant and 96% effective at preventing severe disease. Similarly, research from Canada suggests that the Moderna vaccine is 72% effective at preventing symptomatic infections after one dose and 96% effective at preventing severe disease.
Vaccines are the best protection available against the Delta variant. The Delta variant is highly contagious and has been infecting more people with the coronavirus than ever before. It is much easier to transmit from person to person, and preliminary evidence suggests that fully vaccinated people infected with the Delta variant can still spread the virus to others. However, vaccinated individuals with breakthrough cases often experience mild symptoms or no symptoms at all and do not typically require hospitalization.
The Delta variant is moderately resistant to vaccines in people who have received just a single dose of the Pfizer or Moderna vaccine. Therefore, it is important for individuals to be fully vaccinated to ensure the best protection against the Delta variant.
Additionally, masks help protect against infection by decreasing the ability to inhale viral droplets. So, even for vaccinated individuals, wearing a mask in indoor spaces and in crowded places can help reduce the likelihood of transmission.

Breakthrough infections in vaccinated people may be contagious
Vaccination is the best protection against the highly contagious and easily transmissible delta variant. The vaccines currently available have proven safe and effective at preventing infection and serious illness. Research from the UK suggests that, after complete vaccination, the Pfizer vaccine is 88% effective at preventing symptomatic infections caused by the delta variant and 96% effective at preventing severe disease. Similarly, research from Canada suggests that, after one dose, the Moderna vaccine is 72% effective at preventing symptomatic infections caused by the delta variant and 96% effective at preventing severe disease.
However, it is still possible for fully vaccinated individuals to get breakthrough infections of COVID-19, including the delta variant. While vaccinated people are protected against severe illness and death, they could still spread the virus. New research suggests that fully vaccinated people with breakthrough infections may be just as likely as unvaccinated people to spread the virus to others. Researchers in Wisconsin analyzed viral loads in nose and throat swab samples and found similar viral loads in vaccinated and unvaccinated patients, with levels often high enough to allow shedding of the infectious virus.
The higher viral load associated with the delta variant may explain the increase in breakthrough cases. According to one study, a patient infected with the delta variant has roughly a 1,000 times higher viral load than those infected with the original coronavirus strain. This increased transmission rate allows the delta variant to travel from person to person in seconds with limited contact.
It is important to note that infections in vaccinated individuals are rare compared to unvaccinated individuals. However, when they do occur, vaccinated people may spread the virus just as easily, especially if they are acting as if they are fully immune and going about their daily lives without masks or other precautions. Therefore, it is crucial for vaccinated individuals to continue taking precautions, such as wearing masks and maintaining social distancing, to prevent the spread of the virus to others.

Vaccines reduce the risk of severe illness, hospitalisation and death
Vaccines are highly effective in reducing the risk of severe illness, hospitalisation and death. Research from the UK suggests that the Pfizer vaccine is 96% effective at preventing severe disease caused by the Delta variant. The Moderna vaccine is also highly effective, with one dose being 96% effective at preventing severe disease.
The Delta variant is much more contagious than the original strain, with a higher viral load, and spreads more easily and quickly. Research has shown that vaccinated individuals who still contract the virus often experience mild symptoms, if any, and do not typically require hospitalisation. The vaccines are doing what they are designed to do: defend against the virus and prevent severe illness.
However, it is important to note that vaccinated individuals can still spread the virus. New research suggests that fully vaccinated people with breakthrough infections are just as likely as unvaccinated people to spread the virus. This is because of the high viral load in the nose and throat, which is often high enough to allow the shedding of the infectious virus.
Despite this, vaccines remain the best protection available against the Delta variant. Public health experts agree that the best solution is to encourage people to get vaccinated, as the vaccines have proven safe and effective at preventing infection and serious illness.

The Delta variant is more contagious than previous strains
The Delta variant is the dominant strain of COVID-19 in the US and is infecting more people than ever before. Experts have noted that this variant is behaving much differently from the strain that took hold last year and is much easier to transmit from person to person. Research has found that the Delta variant is 50% more contagious than the Alpha variant.
The Delta variant is moderately resistant to vaccines in people who have received just a single dose of the Pfizer or Moderna vaccine. However, the vaccines are still highly effective in individuals who are fully vaccinated. Research from the UK suggests that the Pfizer vaccine is 88% effective at preventing symptomatic infections caused by the Delta variant and 96% effective at preventing severe disease. Similarly, research from Canada suggests that the Moderna vaccine is 72% effective at preventing symptomatic infections caused by the Delta variant after one dose and 96% effective at preventing severe disease.
Vaccinated individuals who still get infected with the Delta variant often experience mild symptoms, if any, and do not typically require hospitalization. The mildness of these cases is due to the vaccination doing what it is supposed to do—defend against a virus and prevent severe illness. However, it is important to note that fully vaccinated people infected with the Delta variant can still spread the virus to others.
The best protection against the Delta variant is vaccination. As young children are ineligible for COVID-19 vaccination, ensuring an adequate supply of childcare services will depend on protecting the health of childcare providers.

The Delta variant is infecting more people than ever before
The Delta variant is the dominant strain of COVID-19 in the US and is infecting more people with the coronavirus than ever before. Experts say this COVID-19 variant is behaving much differently than the strain that took hold last year and is much easier to pass from person to person. It has hit some states, like Florida, especially hard. In early August 2021, the state accounted for one out of every five COVID-19 infections, hospitalizations, and deaths in the country.
The Delta variant is more contagious and easily transmissible, with studies suggesting it is about 50% more contagious than the Alpha variant. Research has shown that patients infected with the Delta variant have roughly a 1,000 times higher viral load than those infected with the original coronavirus strain. This increased transmission rate means the Delta variant can travel from person to person in seconds with limited contact.
Vaccination is the best protection against the Delta variant. Research from the UK suggests that, after complete vaccination, the Pfizer vaccine is 88% effective at preventing symptomatic infections caused by the Delta variant and 96% effective at preventing severe disease. The Moderna vaccine, after one dose, is 72% effective at preventing symptomatic infections and 96% effective at preventing severe disease. Vaccines are highly effective at preventing serious illness and death, even in breakthrough cases.
However, it is important to note that even vaccinated people can still spread the virus. New research suggests that fully vaccinated people with "breakthrough" infections may be just as likely as unvaccinated people to spread the virus to others. This is because the higher the amount of coronavirus in the nose and throat, the more likely the patient will infect others. Therefore, even vaccinated individuals should continue to take precautions, such as wearing masks and social distancing, especially in areas with low vaccination rates and high surges of COVID-19 cases.

Frequently asked questions
Yes, being vaccinated helps with the Delta variant. Vaccination is the best protection against COVID-19 and its variants.
Research from the UK suggests that the Pfizer vaccine is 88% effective at preventing symptomatic infections caused by the Delta variant and 96% effective at preventing severe disease. Research from Canada suggests that the Moderna vaccine is 72% effective at preventing symptomatic infections caused by the Delta variant after one dose and 96% effective at preventing severe disease.
Yes, vaccinated people can still spread the Delta variant. However, the likelihood of transmission is reduced when everyone wears a mask in indoor spaces, regardless of their vaccination status.
The CDC says that vaccinated people do not need to wear masks when in public and can resume pre-pandemic activities unless other local regulations are in place. However, depending on your comfort level and underlying health status, you may still consider wearing a mask, especially in crowded spaces.
Yes, it is still important to get vaccinated. Immunity from a natural infection wanes over time, and the Delta variant has been infecting people who have previously been infected. Getting vaccinated 90 days after a natural infection will boost immunity.
