Mariposa Public Health Update On Pfizer Booster, 12 New COVID-19 Cases In Tuolumne

Sponsored by:

The FDA announced its authorization of booster doses of the Pfizer COVID-19 vaccine for certain populations. Mariposa Public Health clarifies the Emergency Use Authorization allows for booster doses in those that received their second dose of the Pfizer vaccine over six months ago, and who fall into one of three categories; 65 years or older, 18 to 64 years old at high risk of severe COVID-19, 18 to 64 years old whose frequent institutional or occupational exposure to SARS-CoV-2 puts them at high risk of serious complications of COVID-19. Public Health further adds regarding the high-risk qualification, “We are gaining more clarity on what specific parameters are for these two categories and hope to have further information available soon.” Public health also notes, “If you did not receive the Pfizer vaccine originally and are wondering about boosters, please stay patient as the data is being gathered and analyzed. We will share updates and information as we receive them. If you have concerns about immunity and are moderately to severely immunocompromised, please visit or speak with your primary care provider or specialist about your specific needs for additional doses. If you are eligible for the Pfizer booster or an additional dose as references above, please visit or call 1-833-422-4255 to schedule an appointment.” Additionally, the Advisory Committee on Immunization Practices (ACIP) completed its meeting today and Mariposa Public Health updates, “They agreed to the boosters of those 65 years and older and made recommendations for those 50 – 64 with underlying medical conditions. They did not recommend vaccinations for those 18 – 49 or those with higher risk institutional or occupations exposure. The next step will be to follow the guidance released from CDPH.” More vaccine information is here.

Long COVID, Calaveras County Public Health shares “A recent study found that 1 in 3 people aged 18+ who tested positive for COVID-19 reported at least 1 symptom 2 months after the positive test. Rates were higher among those 40 and older and those with pre-existing conditions. Symptoms of long COVID include: fatigue, loss of taste or smell, shortness of breath, and muscle or joint aches. The term “long COVID” is used to describe symptoms experienced from weeks to months by persons recovering from COVID. Being fully vaccinated lowers your risk of severe symptoms, hospitalization, and death from COVID-19. People should be vaccinated regardless of whether you already had COVID. It has not yet been shown how long you are protected from getting COVID again after you recover from COVID. Vaccination helps protect you even if you’ve already had COVID. Don’t wait. Vaccinate.”
