The CDC has updated its recommendations to allow a second booster dose of either Pfizer-BioNTech or Moderna COVID-19 vaccines for certain immunocompromised individuals 12 and older and all people over the age of 50.  The second booster must be administered at least 4 months after the first booster. Although the number of COVID-19 Omicron variant infections has been relatively low the past few weeks, Redding Health Department officials say there's an increase in infections of the Omicron sub-variant BA.2 across the northeast and Connecticut. This variant is considered more infectious than Omicron and has caused significant spikes across Europe.
