Why did they get re-infected?
Recently, it was reported some people were re infected with the Covid 19 virus. This was in spite the fact they had been vaccinated. Why did they get re infected?

AS with ALL viruses, they mutate every few months so eventually the original vaccine won't work at all.
This is why people that get flu shots every year still get the flu

The vaccine works by causing your body to produce antibodies that will kill off the COVID virus. Unfortunately every person is different, and in some people the vaccine is not effective. That is why they only give them a rating of about 95%. In about 5% of people it does not trigger the right things to make them immune.
Plus the vaccine has not been around long enough for us to know how long it makes you immune. Your body will stop making the antibody after a certain length of time. Again, that vary with every individual. Some may be protected for months, others only days.

When they say these vaccines are 95% effective that means there is still a 5% chance of getting infected.
