The left-wing browbeating of Americans to get the coronavirus vaccine and accompanying booster shots could be undermining the country’s ability to achieve herd immunity, according to one neuroscientist. That is because while the vaccines injected into our bodies stimulate internal immunity, they don’t prevent vaccinated individuals from contracting the virus through the mucous membranes in their noses and mouths. In contrast, unvaccinated people who have recovered from COVID-19 or have antibodies due to their exposure to infected individuals may be better protected from the virus than the vaccinated, according to Dr. Michael Segal, a neurologist and neuroscientist. “All this has implications for public-health authorities’ determination to achieve herd immunity through vaccination alone,” Segal wrote Monday in a Wall Street Journal Op-Ed. He pointed to a recent outbreak in Massachusetts, where 74 percent of infections occurred in fully vaccinated individuals. There has also been a massive recent outbreak in Israel, where 78 percent of residents 12 and older are fully vaccinated with the Pfizer vaccine.
