Why is the MMR given at 9 months?
Vaccinating infants with a first dose of measles-containing vaccine (MCV1) before 9 months of age in high-risk settings has the potential to reduce measles-related morbidity and mortality. However, there is concern that early vaccination might blunt the immune response to subsequent measles vaccine doses.
How effective are flu vaccines?
A 2012 meta-analysis found that flu vaccination was effective 67 percent of the time; the populations that benefited the most were HIV-positive adults aged 18 to 55 (76 percent), healthy adults aged 18 to 46 (approximately 70 percent), and healthy children aged six months to 24 months (66 percent).
Does the hepatitis A vaccine last a lifetime?
Yes. It is not known for how long protection from one hepatitis A vaccine dose lasts, but it has been shown to last for at least 10 years (29).
How many vaccines do you get in a lifetime?
Currently, 16 vaccines – some requiring multiple doses at specific ages and times – are recommended from birth to 18 years old. Recommended vaccines include: Influenza (annual flu shot) Diphtheria, tetanus and pertussis (DTaP)
Is your immune system weaker after a vaccine?
Also, vaccines do not make a child sick with the disease, and they do not weaken the immune system. Vaccines introduce a killed/disabled antigen into the body so the immune system can produce antibodies against it and create immunity to the disease.
What vaccines need boosters?
All adults need a seasonal flu (influenza) vaccine every year. … Every adult should get the Tdap vaccine once if they did not receive it as an adolescent to protect against pertussis (whooping cough), and then a Td (tetanus, diphtheria) booster shot every 10 years.
How effective is this years flu shot 2020?
21 CDC Morbidity and Mortality Weekly Report, the current influenza vaccine has been 45% effective overall against 2019-2020 seasonal influenza A and B viruses. Specifically, the flu vaccine has been 50% effective against influenza B/Victoria viruses and 37% effective against influenza A(H1N1)pdm09.
How many people died in the US from the flu in 2019?
CDC estimates that influenza was associated with more than 35.5 million illnesses, more than 16.5 million medical visits, 490,600 hospitalizations, and 34,200 deaths during the 2018–2019 influenza season.
How long does Hep A and B vaccine last?
Mathematical models predict that the duration of protection against hepatitis A is likely to be 20–25 years, and possibly lifelong [4, 43]. The duration of protection against hepatitis B is at least 15 years, with current scientific evidence also suggesting lifelong protection .

What vaccines Cannot be given together?
of Different Vaccines If live parenteral (injected) vaccines (MMR, MMRV, varicella, zoster, and yellow fever) and live intranasal influenza vaccine (LAIV) are not administered at the same visit, they should be separated by at least 4 weeks.
What happens if you get the same vaccine twice?
Is there any danger from receiving extra doses of a vaccine? Most of the time, your risk of serious side effects does not increase if you get extra doses of a vaccine. Getting extra doses of oral vaccines, such as rotavirus or typhoid, is not known to cause any problems.
Are vaccinations permanent?
Vaccine-induced immunity fades over time and the loss of protection differs with each disease.
Why do flu shots only have 3 strains?
Trivalent vaccines protect against an influenza A(H1N1) virus, an influenza A(H3N2) virus and one influenza B virus, even though there are two different lineages of B viruses that both circulate during most seasons. Adding another B virus to the vaccine aims to give broader protection against circulating flu viruses.
Is it OK to get hepatitis A vaccine twice?
Is it harmful to have an extra dose of hepatitis A vaccine or to repeat the entire hepatitis A vaccine series? No, getting extra doses of hepatitis A vaccine is not harmful.
Can I still get hepatitis B even if I was vaccinated?
The good news is that hepatitis B is vaccine preventable. This means that after you complete the vaccine series, you cannot contract hepatitis B through any modes of transmission; you are protected for life!
Do measles vaccines last a lifetime?
MMR vaccine is very effective at protecting people against measles, mumps, and rubella, and preventing the complications caused by these diseases. People who received two doses of MMR vaccine as children according to the U.S. vaccination schedule are usually considered protected for life and don’t need a booster dose.
