Moderna suggests fully vaccinated people should get booster shots 6-8 months after final dose

Moderna says people who received its Covid vaccine last year are nearly TWICE as likely to get a breakthrough infection compared to those who got the shot recently

People who received Moderna Inc’s COVID-19 vaccine last year are nearly twice as likely to develop a breakthrough infection as those who were recently vaccinated, according to the company.

Breakthrough cases occur when people contract the disease 14 days or more after receiving their final dose of the vaccine.

According to new data released on Wednesday, there were 88 new cases of COVID-19 among Americans who were vaccinated between December 2020 and March 2021.

In comparison, there were 162 cases – 1.8 times as many – among those who were vaccinated between July and December 2020.

In addition, the Cambridge, Massachusetts-based company reported 13 severe cases in the early vaccination group versus six in the later group.

Furthermore, three Covid hospitalizations and two deaths occurred in the vaccinated group last year, compared to no hospitalizations or deaths in the vaccinated group in winter 2020 and spring 2021.

According to Moderna, the findings support the administration of booster doses to fully vaccinated individuals.

The study looked at people who took part in Moderna’s Phase 3 COVE study last year, as well as those who received the vaccine after it was approved for emergency use by the US Food and Drug Administration (FDA).

There were 162 breakthrough Covid cases among the 14,746 people who received the vaccine between July 2020 and December 2020.

In comparison, from December 2020 to March 2021, there were 88 breakthrough cases among the 11,431 people who received the vaccine.

According to the researchers, this means that those who received their first dose 13 months ago have 36% less protection than those who received their first shot eight months ago.

For both groups, more cases were seen among younger adults.
