    Moderna booster is already on trial. They announced in May that early human trials showed that a third dose of either its current COVID-19 vaccine or an experimental, variant-specific shot increased immunity against the Beta and Gamma variants, first found in South Africa and Brazil, respectively.

    The mRNA vaccines can easily be modified for variants but the issue is it still need to go through a limited trial phase to be authorized. Takes time.

    I took the Moderna. the side effects are really bad after the second vaccine.😞😞😞It was like I got hit by a car. I hope this side effects won't be continued with booster shots. But this is only 20 hours. after that all are vanish.
