The vaccines developed by Pfizer with German partner BioNTech and Moderna using mRNA technology may offer protection against the coronavirus-borne illness COVID-19 for years, according to a new study published Monday.
The study, conducted by researchers at Washington University in St. Louis, suggests that people vaccinated with those shots may not need boosters, as long as the virus does not mutate or give rise to new vaccine-resistant variants. It also found that people who have recovered from COVID before being vaccinated “produced the most robust serologic responses,” showing they enjoy a strong immune response.
The study has been peer-reviewed, according to Nature, although it published it before copy editing and proofing.
