(CNN) Health experts have said that data so far has shown that Covid-19 vaccines prevent symptoms of the virus — but a new study suggests that the Moderna and Pfizer vaccines may also prevent infections.
A team at the Mayo Clinic health system looked at more than 31,000 people across four states who had received at least one dose of either vaccine — and found their vaccines were upwards of 80% effective in preventing infection 36 days after the first dose.
Vaccine efficacy was 75% 15 days after the first dose, and appeared 89% effective from 36 days after the second dose, according to the research, which has not yet been peer-reviewed.
Despite a backlog in inoculations due to harsh winter weather that has gripped much of the US, officials have been pressing to vaccinate Americans before what appear to be more transmissible variants, which they fear could reverse the progress in terms of lowering cases and hospitalizations.
