It's still used where polio is endemic. The U.S. has used the Salk vaccine since 2000. Withered limbs from polio have been documented since early man: note the Egyptian priest's withered left leg.

I am almost 27. Will it help to still get the hpv vaccine if there are signs of the virus present?

HPV vaccine: The HPV vaccine (Gardasil) is excellent at preventing HPV caused by any of 9 different HPV types. However, it has no effect at all on an HPV infection someone already has. The vaccine is not normally recommended beyond age 26, but is harmless and still effective in people at risk for future exposure. ...Read more

Born in 1975. I think I got measles vaccine but not sure type (live or killed virus) and if got 1 shot or 2. Do I need get current MMR vaccine?

MMR for adults: Persons vaccinated before 1979 with either killed mumps vaccine or mumps vaccine of unknown type who are at high risk for mumps infection should be considered for revaccination with 2 doses of MMR vaccine.

Vaccine for hep B does it mean I woudnot never get the virus even if I exposed to it from patient with virus? Is there also booster vaccine and when?

Vaccine for hep B does it mean I woudnot never get the virus even if I exposed to it from patient with virus? Is there also booster vaccine and when?

You need to get the: Whole vaccine sequence in order to be protected. It has a series of 2 boosters in short sequence from the initial vaccine. Your body's immune system needs to recognize it, to react to it, and if you're missing the sequencing, then you're inadequately protected. It's not like tetanus shot, where you need a booster every 10 years. You just need to complete it once. Adolescent dosing is different. ...Read more

5 month old chest cough due to virus, took 3 days bretaped oral steroid friday. Still coughing temp 37.7. How long can cough last? Vaccines due... Ok?

Vacicnes-no: Coughing can last 7-10 days from a virus. Steroids indicate there was probably wheezing as well. If the cough is the same as when steroids started then be seen again to be sure the wheezing is gone. I prefer not to vaccinate until the illness is resolved. I do not llke to overtax the immune system. ...Read more

Is it possible to be exposed to flu virus in small enough amounts to not get sick but develop some antibodies? Not to undermine vaccine. Curious.

Is it possible to be exposed to flu virus in small enough amounts to not get sick but develop some antibodies? Not to undermine vaccine. Curious.

I'd: Interesting question. There do exist subclinical infections that produce little or no symptoms but result in antibodies. The flu is caused by different viruses such as bird or swine so difficult to answer exposure rate. However my best guess we be it is possible but would not count on it. Better to get the vaccine! ...Read more

If I have a HPV 9-valent vaccine now&in future a better vaccine came out against more strain of the virus, can I still have the better vaccine? 17 male

Yes, you can.: Since vaccines are merely pieces of antigen that your immune system reacts to and develops its own antibodies to, there should be no scientific reason why you would be unable to receive a new vaccine in the future with a higher number of valences. ...Read more

Should flu vaccine be taken annually is necessary for us? Who always can't predict the right strain for vaccine, we still suffer from the novel virus.

Get shot annually: The flu virus changes, so it's important to get vaccinated every year. The cdc usually does a pretty good job of predicting which viruses will be circulating. Sometimes they miss, but if you don't get the shot you have no chance of being protected. ...Read more

If shingles is caused by chicken pox virus, why do they say let your kid get chicken pox or get the vaccine? Wouldn't that increase your risk of shingle

If shingles is caused by chicken pox virus, why do they say let your kid get chicken pox or get the vaccine? Wouldn't that increase your risk of shingle

Risk benefit ratio: Prior to the vaccine we had about 10, 000 hospital admissions & 50 deaths/yr with chickenpox. Deaths have dropped to none in the vaccinated group. The frequency of shingles after the shot is less than that of wild disease. Shingles emerges when the persons immune system fails to keep it in hibernation. Though nasty, it is not a fatal disease but would be more frequent without the vaccine. ...Read more

When you get a flu vaccine do they inject a small amount of the flu virus into you?

When you get a flu vaccine do they inject a small amount of the flu virus into you?

Not really: What they do is grow a lot in the lab, harvest the particles and kill it. By injecting the equivalent of dead virus into your body your immune system develops antibodies to the outside shell of the virus. It is not alive and cannot give you the flu. ...Read more

My mom got shingles 8 days ago. I'm 18, never had chickenpox, but had the vaccine 2x. Can I get the virus? I had no direct contact w/ her blisters&rash

I wouldn't worry: The 2 doses of vaccine places you in the 95% range of having immunity to CPX. The shingles also differs from regular CPX by not passing in the air if you were in the room with her. To be exposed, a vulnerable person would need direct contact to debris from the wounds. ...Read more

If I have a high risk of cancer since it runs in my family should I get the HPV vaccine or is that just for the STD virus?

Get vaccinated: Even with your family history, you're probably not at increased risk of HPV-related cancers. But all people should get the vaccine that prevents 4 of the genital HPV types, especially at your age, regardless of apparent risk. The frequency of genital HPV and HPV-related cancers is the same in people with very few and very many sex partners. Why take any risk when it's so easily prevented? ...Read more

What are the cons of the gardisil shot? Is this vaccine injecting u with the HPV virus?

No Cons: The Gardasil shot is a vaccine that protects you against two low risk hpv types and two high risk types of hpv. The vaccine does not contain any virus. It is quite safe. In my opinion, there is no downside except cost as insurance companies in my state do not cover Gardasil over the age of 26. ...Read more

If vaccines are made from viruses, why do they not make us sick?

If vaccines are made from viruses, why do they not make us sick?

Much research: Vaccines will often take 2 decades of research before they come to market. In that interval, the researchers determine whether a weakened/ killed or synthetic material that replicates parts of the virus will trigger a protective immune response. The weakened virus (nasal flu, MMR, varicella) all have some potential to cause a low grade infection. Killed or synthetic material does not. ...Read more

Why is a virus treated with a vaccine and not a drug?
