[ARCHIVED] COVID-19 Bivalent Moderna Booster clinics offered at the Greenwich Department of Health

 10.08.2022 Press Release for COVID-19 Bivalent Moderna Booster Clincs

COVID-19 Bivalent Moderna Booster Clinics Offered on October 11th and 19th

 The Greenwich Department of Health will be offering the approved updated COVID -19 Bivalent Booster Vaccine (Moderna) for adults 18 years and older at two scheduled clinics in October 2022.   The new COVID-19 Booster Vaccine targets two versions of the coronavirus, the original strain and the Omicron sub-variants (BA. 4 & BA.5), which became the dominant subvariants in the U.S over the summer. Accordingly, to federal health officials most of the population should plan on getting an updated COVID-19 shot matched to the strain of the virus that is currently circulating.  

The Bivalent Booster Vaccine has been authorized for people 12 years to 17 years old for Pfizer vaccine and 18 years and older for Moderna or Pfizer vaccine. In addition, persons must have had their last vaccine COVID-19 Booster shot or their last vaccination of the Pfizer, Moderna vaccination series or the one initial vaccination of Johnson and Johnson vaccine at least 2 months (8 weeks) past the last shot to receive the Bivalent Booster vaccine.  If a person is getting vaccinated for the first-time, they need to get the original COVID-19 vaccine and not a Booster Vaccination.  Accordingly, to the CDC the new mRNA Booster vaccine (Moderna and Pfizer) will provide better protection against serious illness, hospitalization and death. The previous COVID-19 Booster Vaccines only targeted the original version of the coronavirus. Director of Health Caroline Calderone Baisley says, “Getting the new Bivalent Booster Vaccine is a step in the right direction for better protection against the COVID-19 subvariants that are in circulation.  Omicrons subvariant BA. 5 is highly contagious and if you got COVID-19 disease prior to the subvariants circulation you can get COVID-19 again if exposed to the subvariant. In addition, if you had a booster shot or several boosters shots in the past, the subvariant BA. 5 has the ability to break through a person’s immunity very successfully.  Booster vaccinations bolster the bodies antibody levels to fight infection. Prior to the Omicron Virus variant arriving late in December 2021 reinfection of COVID-19 disease was rare.  However, once Omicron emerged immunity gained from prior COVID-19 infection and vaccinations only provided 50% protection against reinfection.”
