Vaccines are an important way to protect oneself and their loved ones from preventable diseases. While most people are vaccinated as children, adults may require additional vaccines or boosters to maintain protection. This is because the protection provided by some vaccines can fade over time, and new vaccines are also constantly being developed. As such, adults should check with their primary care provider to ensure they have received all the necessary doses for vaccines they may have received as children or teenagers. This is especially important for adults who are at increased risk for certain illnesses due to age, job, health conditions, or travel plans.

Adults born before 1957 are assumed to have measles immunity
It is assumed that adults born before 1957 have been exposed to measles in their childhood and are, therefore, immune to the disease. This is because measles was highly contagious before 1957, and almost everyone contracted it before they turned 15. Hence, adults born before 1957 are presumed to have lifelong immunity and do not need to get vaccinated. However, it is recommended that these adults consult with their healthcare provider and get a blood test done to determine their immunity.
On the other hand, adults born after 1957 would have received the measles vaccine as children and are considered protected for life. However, if they are unsure about their immunity, they should try to find their vaccination records or get a blood test done to determine their immunity. If they are not immune, they should get vaccinated with the measles-mumps-rubella (MMR) vaccine.
The measles vaccine is essential in creating immunity without the risks of severe infection. The immunity from the vaccine is similar to the immunity gained from contracting the disease. However, the vaccine is much safer than contracting the disease as it contains a weakened strain of the measles virus. This strain is too weak to cause measles but is similar enough to train the immune system to recognize and fight off the wild-type virus.
Vaccines are crucial in protecting oneself and one's loved ones from preventable diseases. They help the body create protective antibodies that fight off infections. Vaccines have greatly reduced diseases that once routinely harmed or killed babies, children, and adults. Hence, it is essential to get vaccinated to protect oneself and others from harm.

Adults may need a second measles dose if vaccinated between 1963-1967
The measles, mumps, and rubella (MMR) vaccine is considered the best way to protect oneself from these preventable diseases. While most people were vaccinated for a number of diseases as children, it can be challenging for adults to recall the specific vaccines they received decades ago, and medical records can be difficult to locate.
For those who received the measles vaccine in the 1960s, it is important to determine whether revaccination is necessary. The Centers for Disease Control and Prevention (CDC) recommends that individuals vaccinated before 1968 receive at least one dose of the live attenuated vaccine. This is because the inactivated (killed) measles vaccine, which was available from 1963 to 1967, was ineffective. Therefore, adults who were vaccinated during this period may need a second measles dose to ensure adequate protection.
If you were vaccinated between 1963 and 1967 but are unsure which version of the vaccine you received, it is advisable to consult your vaccination records. However, if written documentation is unavailable, or if you have not undergone a blood test to confirm immunity, the CDC suggests receiving another dose or two of the MMR vaccine. This is a safe option, and there is no harm in receiving an additional dose if you are already immune.
It is worth noting that the need for a second measles dose also depends on your travel plans and exposure risk. The CDC recommends two doses of the MMR vaccine for anyone planning international travel, as travellers are at high risk for exposure and transmission of measles. Additionally, adults over 20 are more susceptible to developing complications from measles, such as pneumonia and brain swelling, further emphasising the importance of ensuring complete vaccination.

Adults should get the Tdap vaccine if they didn't as adolescents
Vaccines are the best way to protect oneself from certain preventable diseases. They help the body create protective antibodies—proteins that fight off infections. The Tdap vaccine is a combination vaccine that contains more than one vaccine in the same shot. It is a vaccine for tetanus, diphtheria, and pertussis (whooping cough). Tetanus affects the brain and nervous system and causes painful muscle spasms, especially around the neck and jaw, a condition often called "lockjaw". Diphtheria is a highly contagious infection that causes difficulty in breathing and, in severe cases, can lead to heart and nerve damage and even death. Pertussis, or whooping cough, is a respiratory infection that can cause severe breathing problems, especially in infants. It first appears like a common cold but then causes intense coughing fits.
The Tdap vaccine is for anyone aged 7 and older. Preteens (aged 11 or 12) should get the Tdap vaccine to boost their immunity. Adults who have never received the Tdap vaccine should get a dose of Tdap. After the initial dose, a Tdap or Td booster shot is recommended every 10 years for life. The Td vaccine protects against tetanus and diphtheria but not whooping cough. The Tdap vaccine is available at most pharmacies, urgent care centres, doctors' offices, and community health clinics. The CDC says everyone should be vaccinated for tetanus, diphtheria, and pertussis.
Pregnant women should get a Tdap shot during the early part of their third trimester. The Tdap vaccine during pregnancy prevents pertussis, which can be life-threatening for the baby. It helps protect the baby from whooping cough until they are old enough to get their own vaccine. Studies have shown there are no safety issues with the Tdap vaccine during pregnancy. Getting the vaccine does not cause any risks to the baby, including premature birth or low birth weight.
If you are not insured and cannot afford to pay for a Tdap vaccine, there are some options to help you get the vaccination for free. The U.S. Department of Health and Human Services website lists federally funded centres and each state's health department, where you can find information for free and low-cost vaccines in your area.

Adults at risk of hepatitis B should get vaccinated
Vaccines are a safe and effective way to protect yourself and your loved ones from preventable diseases. While most people are vaccinated for several diseases as children, adults are also at risk for some vaccine-preventable diseases. For instance, adults at risk of hepatitis B should get vaccinated. Hepatitis B is a serious, potentially deadly infection of the liver caused by the hepatitis B virus (HBV). There is no cure, but vaccination can prevent HBV infection and the chronic liver damage and cancer that hepatitis B can cause.
The World Health Organization (WHO) recommends the hepatitis B vaccine for all newborns, children up to 18 years of age, and all adults at higher risk of infection. The U.S. Centers for Disease Control and Prevention (CDC) recommends the hepatitis B vaccine for all newborns, children up to 18, adults aged 19-59, and adults 60 and older who are at high risk of infection. The Advisory Committee on Immunization Practices (ACIP) recommends hepatitis B vaccination for adults aged 19-59 and adults 60 and older with risk factors for hepatitis B or without identified risk factors but seeking protection.
The hepatitis B vaccine is safe for pregnant women and is also recommended for adults living with diabetes and those at high risk of infection due to their jobs, lifestyle, living situations, or country of birth. If you are unsure whether you fall into one of these categories, talk to your doctor about getting vaccinated. If you are an adult seeking protection from HBV infection, you do not need to acknowledge a specific risk factor to get the vaccine.
The hepatitis B vaccine is a series of two or three shots, depending on the brand. The safety and effectiveness of the Heplisav-B vaccine have not been established for adults on haemodialysis. If you miss a dose of the hepatitis B vaccine, it is okay—just be sure to get the next dose as soon as possible.

Adults need annual flu vaccines, especially those over 65
Vaccination is one of the best ways to protect oneself from certain preventable diseases. Vaccines help the body create protective antibodies, which help fight off infections. While most people tend to associate vaccines with children, adults are also at risk for some vaccine-preventable diseases.
The flu vaccine is one such vaccine that is recommended for adults, especially those over 65. Influenza, or the flu, is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and lungs. While everyone aged 6 months and older should get an annual flu vaccine, it is especially important for adults over 65 as they are at a higher risk of developing serious flu complications. During most flu seasons, people 65 and older bear the greatest burden of severe flu disease. They are also more likely to experience flu-related complications such as pneumonia, heart attacks, or strokes, which can be life-threatening.
The flu vaccine helps to avoid infection and reduces the chances of hospitalization or death if one does get infected. It is important to get the flu vaccine by the end of October each year, as flu season typically peaks in December or January. However, even if one misses the October deadline, it is still beneficial to get vaccinated as long as the flu virus is spreading. For adults 65 and older, there are three preferentially recommended flu vaccines: Fluzone High-Dose inactivated flu vaccine, Flublok recombinant flu vaccine, and Fluad adjuvanted inactivated flu vaccine. These higher-dose or adjuvanted vaccines are potentially more effective than the standard-dose vaccine for this age group.
In addition to the flu vaccine, there are other vaccines recommended for adults, such as the Tdap (tetanus, diphtheria, and pertussis) vaccine, which is recommended for adults who did not receive it as adolescents. Overall, it is important for adults, especially those over 65, to stay up to date with their vaccinations to protect themselves and their loved ones from preventable diseases.
