I had the johnson & johnson vaccine last july. when do the antibodies start to wane or completely leave?

Most of the antibodies have diminished by now. You need a booster now and possibly another in 6-8 months.

Antibodies to Covid-19 start to fade in about 6 months. It would be prudent to get a booster dose. Also get Flu vaccine.

Hello, Can anyone get a booster after only 1 vaccine shot instead of two. This is not regarding Johnson and Johnson which is only 1 shot. This is Pfizer. With one dose, can you skip the second and eventually get a booster? Or is two mandatory first?
