According to Santa Barbara County COVID-19 data, on Nov. 11, 149 fully vaccinated people contracted COVID-19. In San Luis Obispo County, 23% of fully vaccinated people contracted the virus, a cumulative rate since June this year. But what could be the cause of these numbers?
“We know from some data that the vaccine will decline in 6-9 months. In particular, the older you get, the more the vaccine will decline. People who are 65 years old will decrease from 90% effective to 60% effective rate after about 6 months,” said Dr. Thomas Vendegna, medical director of the French Hospital Medical Center.
Local health officials say there may be a solution to achieve a stronger COVID-19 immune response.
“The booster will bring you back to 90%. I highly recommend the booster, especially for older people,” said Vendegna.
The director of the US Center for Disease Control and Prevention, Dr. Rochelle Walensky, said the data shows the effectiveness of booster shots.
“If we compare the rates of COVID-19 disease between those vaccinated with two doses and those who received a booster dose, the disease rate is significantly lower. For those who received their booster injection, it demonstrates that our boosters work” Walensky said.
As the holiday season approaches, health officials say safety precautions will become increasingly important.
“We may be mixing with people who haven’t been vaccinated,” Vendegna said. “So I really emphasize those other options, like wearing a mask and being outside, limit your gatherings to smaller gatherings, especially if you know their vaccination rates.”
In both Santa Barbara and San Luis Obispo County, the booster shot is available to all adults 18 years of age or older. Boostershot appointments can be made via this website.
