Even with the Delta variant now present, vaccinated people are less likely to spread COVID-19 to others. Vaccinated people are also more likely to have milder cases if they are infected after the vaccine, and less likely to die from the virus. Covid is not over yet, if you've been vaccinated, please remember to get your booster shot. I had Moderna and will get the Moderna booster, my husband got J&J and will get the Moderna booster if possible for him.

People who are vaccinated against Covid-19 are less likely to spread the virus even if they become infected, a new study finds, adding to a growing body of evidence that vaccines can reduce transmission of the delta variant.
“People who have been vaccinated will have immune systems at the ready that can coat the virus in antibodies much more quickly than unvaccinated people who have to build up an immune response,” Richterman said.
The new study showed that protection against transmission seemed to wane over time, however. After three months, people who had breakthrough infections after being vaccinated with AstraZeneca were just as likely to spread the delta variant as the unvaccinated. While protection against transmission decreased in people who had received the Pfizer vaccine, there was still a benefit when compared with people who were unvaccinated.
Since antibody levels also tend to decrease over time after vaccination, a reduction in protection against transmission is to be expected, Richterman said.
“We know that the amount of antibodies circulating in the blood decreases over time after vaccination, even though the immune memory remains durably robust and is still able to prevent infections, particularly severe infection,” he said. “These circulating antibodies that are immediately available probably play some role in preventing transmission if infected, so I don’t think it’s surprising to see some reduced protection against transmission over time.”
