CDC COVID-19 Response Team published a weekly report on Friday where a vast majority of the patients infected with the Omicron variant identified in the US so far were fully vaccinated individuals.
The U.S. Centers for Disease Control and Prevention (CDC) reported that of the 43 COVID-19 cases caused by the Omicron variants, 34 people were fully vaccinated. Of those fully vaccinated, 14 people had received their booster shots but five of those received their additional shots less than 14 days.
Only 8 people were unvaccinated who got infected with the Omicron variants and 1 person has status unknown.
The CDC added that the “mutations in Omicron might increase transmissibility, confer resistance to therapeutics, or partially escape infection- or vaccine-induced immunity.” This means the vaccines offer less protection against Omicron.
Details are available for 43 cases of COVID-19 attributed to the Omicron variant; 25 (58%) were in persons aged 18–39 years (Table). The earliest date of symptom onset was November 15 in a person with a history of international travel. Fourteen (33%) persons reported international travel during the 14 days preceding symptom onset or receipt of a positive test result. Among these cases of COVID-19 attributed to the Omicron variant, 34 (79%) occurred in persons who completed the primary series of an FDA-authorized or approved COVID-19 vaccine ≥14 days before symptom onset or receipt of a positive SARS-CoV-2 test result, including 14 who had received an additional or booster dose; five of the 14 persons had received the additional dose <14 days before symptom onset. Six (14%) persons had a documented previous SARS-CoV-2 infection. The most commonly reported symptoms were cough, fatigue, and congestion or runny nose. One vaccinated patient was hospitalized for 2 days, and no deaths have been reported to date. Case investigations have identified exposures associated with international and domestic travel, large public events, and household transmission.
The Gateway Pundit previously reported that a government-funded project showed that the effectiveness of vaccines significantly waned over time. The effects lessen in any fully vaccinated individuals with each passing week.
Also, a study published in the New England Journal of Medicine and conducted in Israel during the Delta surge found that the immunity against the delta variant of SARS-CoV-2 waned in all age groups a few months after receipt of the second dose of vaccine.
