Moderna vaccine still effective months later

While the data appears to show that the vaccine will remain effective, company officials say there may still be a need for a COVID-19 booster shot.
“We believe that increased force of infection resulting from Delta, non-pharmaceutical intervention (NPI) fatigue, and seasonal effects (moving indoors) will lead to an increase of breakthrough infections in vaccinated individuals,” the company said in an investor presentation posted to its website, NBC News reported.

The average COVID-19 cases nationwide are now running in excess of 120,000 a day.
Although some of those are breakthrough cases in the previously vaccinated, the CDC warns that the unvaccinated are 8 times more likely to contract Delta and 25 times more likely to die from it, reported NBC.
