The most effective step in fighting Covid-19 is vaccination. But even people who have received two shots might only have 30 percent protection against the new omicron variant. Adding a booster to those two shots “boosts” the protection up to approximately 80 percent, according to reports.
More than 70% of Alexandrians are fully vaccinated, but only 28% of those have been boosted.
Overlapping strategies to avoid infection work best, so in addition to vaccination and booster shots, wear a mask when indoors in public, and get tested if you’ve been exposed or have symptoms.
Case numbers for Covid-19 are rising sharply in Alexandria. There were 145 new cases on Dec. 18; 156 new cases on Dec. 19; 141 new cases on Dec. 20.
