If you already survived covid why would you need a vaccine?

Question

I dont get flu shots either, im still alive

Update:

if covid immunity only lasts 3 months then why havent I been reinfected this entire time

Update 2:

flu shots never cancelled the flu

Answer 1

Because you CAN get it again, stupid.  Or, don't & die.  We don't care either way.  

Answer 2

Many who had Chicken pox still needed the vaccine to keep them safe as they aged. Immunity, antibodies are a funny thing. Sometimes the body makes enough to keep one from being reinfected, and other times. They do not. Some people make smart antibodies that can recognize a virus or a relative to a virus and get busy right away. Others seem to produce moron or lazy antibodies that don't seem to do an aweful lot until the infection becomes out of hand.

Answer 3

Vaccine reliably conveys immunity, being infected doesn't. There are cases of people being mildly infected and then becoming more seriously infected because the first infection didn't produce enough antibodies. Flu is serious for people who are old or have health problems like asthma. Vaccination reduces the risk of a serious cases which could tie up hospital beds.

Answer 4

Because COVID isn't a once in a lifetime thing like mumps.  It can repeat.  So the vaccine will be used to break the infection cycle.  It's like setting a back-burn to fight a forest fire.

Answer 5

Covid immunity only lasts for about 3 months. 

Answer 6

There isn't 100% evidence thst having covid actually provides effective antibodies in all individuals. 

Just like any and every vaccine not being 100% effective. 

Although it's extremely rare, some people have already had covid twice.
