Went in for a pneumonia shot and landed up here with fluid in my bicep. I’ll be ok but it’s important that you keep an eye on who’s giving the shot and make sure they not only swab the spot correctly but that you watch the needle come out of the package.
According to WebMd:
You cannot get pneumonia from the vaccine. The shots only contain an extract of the pneumonia bacteria, not the actual bacteria that cause the illness.
But some people have mild side effects from the vaccine, including:
Swelling, soreness, or redness where you got the shot
Fussiness or irritability
Loss of appetite
Fewer than 1% of people who get the pneumonia vaccine have these types of side effects. Allergic reactions are even rarer.
