Three are nucleic-acid vaccines with genetic material such as DNA and RNA of the antigens. Four are protein subunit vaccines. These vaccines contain the recombinant protein of SARS.COV-2 and an adjuvant (booster). How long does it take for a vaccine to be developed? The process of developing a vaccine is complex and long.
