Vaccines are a safe and effective way to protect yourself and your community from preventable diseases. While the COVID-19 vaccine does not guarantee that you won't catch the virus, it does provide the best possible immunity by reducing the chances of severe illness, long-term effects, and hospitalization. This is especially important for those who are immunocompromised or at high risk of severe illness, such as those with cancer or other underlying health conditions. In addition to vaccination, preventative measures such as wearing masks and social distancing can also help lower the risk of COVID-19 transmission.

What You'll Learn
Vaccines protect against preventable diseases
Vaccines are the best way to protect yourself and your loved ones from preventable diseases. They have greatly reduced diseases that once routinely harmed or killed people of all ages. Vaccines have been proven to be safe and effective, and they are required for many everyday activities such as school and work, as well as for travel to many places around the world.
Vaccines work by exposing the body to killed or weakened bacteria or viruses, or important pieces of them, which helps the body fight infection and strengthen its natural defences. This exposure results in vaccine-induced immunity, which can also be achieved through passive immunity, where antibodies are produced by another human or animal. Active immunity takes longer to develop but lasts longer, whereas passive immunity provides immediate protection that fades within weeks or months.
The number of doses needed to achieve immunity depends on whether the antigen in a vaccine is alive or not. Live-attenuated vaccines, which contain living bacteria or viruses, can provide enduring protection with only two doses. On the other hand, non-live vaccines typically require at least three doses to achieve protection, and this protection fades over time, requiring booster doses.
Vaccines have been successful in reducing the prevalence of many preventable diseases. For example, the chickenpox vaccine has made the disease less common today, and the measles vaccine has saved millions of lives and prevented significant suffering globally. Vaccines are also available for diseases such as hepatitis B, human papillomavirus (HPV), and seasonal influenza (flu), providing protection from serious complications and consequences that these diseases can cause.

Vaccines reduce the risk of severe illness
Vaccines are an effective way to reduce the risk of severe illness and protect yourself from preventable diseases. Vaccination helps to prevent severe forms of illnesses and lowers the chances of hospitalization or death. For example, the annual flu vaccine not only helps to avoid infection but also reduces the risk of flu-related complications such as pneumonia, heart attacks, or strokes. Similarly, the COVID-19 vaccine may not prevent catching the virus, but it protects against severe illness and lowers the risk of long-term effects.
Vaccines are especially crucial for individuals with weakened immune systems, such as those with cancer or other serious health conditions. By getting vaccinated, they can protect themselves and avoid severe health issues. Vaccination is also essential for those who cannot get vaccinated due to age or other factors. When more people around them are vaccinated, the risk of these vulnerable individuals contracting preventable diseases decreases significantly.
Vaccines have a proven track record of reducing diseases that once routinely harmed or killed people of all ages. For instance, the chickenpox vaccine has made the disease less common, and the measles vaccine has saved millions of lives globally. Vaccination against these illnesses protects children and adults alike and prevents severe complications.
Furthermore, vaccines are often required for school, work, travel, and other activities. Many countries mandate specific vaccines for students, military personnel, healthcare workers, and residents of care centers to prevent the spread of diseases in high-risk settings. By staying up-to-date with recommended vaccinations, individuals can protect themselves and comply with the requirements for various activities.
Overall, vaccines play a crucial role in reducing the risk of severe illness by boosting immunity and providing protection against preventable diseases. They help to safeguard individuals and communities, especially those who are vulnerable or unable to get vaccinated themselves.

Vaccines can prevent serious complications
Vaccines are a safe and effective way to protect oneself and one's community from preventable diseases. They have been proven to reduce serious illnesses and deaths, especially in babies, children, and adults. Vaccines are so important that they are required for school, work, travel, and other everyday activities.
Hepatitis B is a serious and potentially deadly liver infection with no cure. However, vaccination can prevent HBV infection and the chronic liver damage and cancer associated with it. Similarly, the HPV vaccine protects against cervical cancer and other cancers in both women and men.
Vaccines also help prevent rare but severe complications from diseases like measles, mumps, and pneumococcal disease. Measles and mumps can lead to hearing loss, infertility, blindness, and intellectual disability due to nervous system damage. Pneumococcal disease is a leading cause of pneumonia in children under five, which can be fatal.
Furthermore, vaccines like the Tdap protect against serious bacterial and throat infections such as tetanus, diphtheria, and pertussis (whooping cough). Tetanus can cause stiff muscles and breathing problems, while diphtheria can lead to nerve damage, heart problems, and difficulty breathing.
In summary, vaccines are a critical tool to safeguard individuals and communities from preventable diseases and their severe complications. They have been proven to reduce hospitalizations, deaths, and long-term health issues, making them an essential component of public health and disease prevention.

Vaccines may be required for certain activities
Vaccines are one of the best ways to protect yourself and your community from preventable diseases. They have greatly reduced diseases that once routinely harmed or killed people of all ages. Vaccines are safe and effective, even for those taking prescription medications.
In the context of the COVID-19 pandemic, new federal restrictions on vaccine eligibility caused confusion and frustration among those trying to get vaccinated. The eligibility criteria varied from state to state, and some people were denied the vaccine due to their age or health status. However, it is important to note that vaccination is crucial for those with cancer or a weakened immune system, as they are at higher risk of severe illness from COVID-19.
Vaccines are also critical for people with chronic health conditions, such as diabetes, heart disease, lung disease, liver disease, and HIV infection. These individuals are at higher risk of serious complications or death from vaccine-preventable diseases. For example, the flu vaccine can reduce the chances of hospitalization or death and protect against flu-related pneumonia, heart attacks, or strokes.
Additionally, certain vaccines are required for immigration purposes to the United States. Refugees are not required to be vaccinated before arrival, but they can start getting vaccinated through a program for U.S.-bound refugees. Adoptive parents of children under 10 years old can sign an affidavit stating that the child will be vaccinated after arriving in the U.S., while parents of older children must provide proof of vaccination during the overseas medical examination.

Vaccines help protect those who can't get vaccinated
Vaccines are a safe and effective way to protect oneself from preventable diseases. They are rigorously tested and continuously monitored for safety and effectiveness. While they do not provide full protection, they significantly reduce the chances of infection and prevent severe illness and hospitalisation. Vaccines have saved countless lives and reduced diseases that once routinely harmed or killed people of all ages.
However, not everyone can get vaccinated due to age or underlying health conditions. For example, newborns and young children in conflict-affected areas, such as Sudan, may not have access to vaccines due to a lack of health facilities or awareness among caregivers. Similarly, in the context of COVID-19, federal restrictions have limited vaccine eligibility to individuals most vulnerable to severe illness, often those above a certain age or with specific health issues.
In such cases, vaccines play a crucial role in protecting those who cannot get vaccinated. When a significant portion of the community is vaccinated, the risk of disease transmission decreases, creating a protective barrier around those who are unvaccinated or immunocompromised. This concept is known as herd immunity, where high vaccination rates make it difficult for a disease to spread, indirectly safeguarding those who are unable to receive the vaccine.
Vaccines also help prevent the spread of preventable diseases, further protecting those who cannot be vaccinated. For example, the flu vaccine not only reduces the likelihood of infection but also lowers the chances of transmitting the flu to others. Thus, when individuals get vaccinated, they contribute to the protection of their community, especially those who are vulnerable or unvaccinated.
Moreover, vaccines can reduce the long-term effects of certain infections. For instance, the HPV vaccine not only prevents immediate infection but also protects against the various cancers that HPV can trigger in the future. By getting vaccinated, individuals can lower their risk of developing severe health complications from preventable diseases, even if they are unable to receive a specific vaccine.
