If you are pregnant and unvaccinated, you have a higher risk of severe illness from COVID-19. Your baby may also have a higher risk of premature birth (before 37 weeks of pregnancy).If you cannot have the Pfizer vaccine, you can talk to your doctor about if the Novavax vaccine is right for you.Real-world evidence has shown that the Pfizer vaccine is safe if you are pregnant and breastfeeding.If you are trying to become pregnant, you do not need to delay vaccination or avoid becoming pregnant after vaccination.If you are pregnant, you can get vaccinated with the Pfizer vaccine at any stage of pregnancy.The Australian Technical Advisory Group on Immunisation (ATAGI) has provided the following advice on the use of COVID-19 vaccines during pregnancy: checking each batch meets quality standards.working with international regulators to share knowledge.collecting and reporting data on side effects.The TGA monitors COVID-19 vaccine safety by: Tien reported no disclosures.īrittany Vargas is a medicine, mental health, and wellness journalist.The Therapeutic Goods Administration (TGA) has a vaccine approval process that carefully assesses a vaccine's safety.

This study was funded by the CDC through contracts with participating sites. 'I always tell patients, with any vaccine, immunization is one of the biggest bangs for your buck in healthcare because you're preventing a problem,' Tien said. But those effects, such as muscle pain, nausea, and fever, are mild compared to shingles. Just like with any other vaccine, patients sometimes have concerns about the potential side effects of RZV, said Tien. The CDC estimates that up to 18% of people with shingles experience PHN, and the risk increases with age. Complications like postherpetic neuralgia (PHN) - characterized by long-term tingling, numbness, and disabling pain at the site of the rash - can interfere with the quality of life and ability to function in older adults.

The risk for HZ increases with age, reaching a lifetime risk of 50% among adults aged 85 years. But interim findings from another study following people in clinical trials found VE levels remained high after 7 years. Adults older than 19 years who are immunocompromised should receive two doses of RZV separated by 1-2 months, the agency said.Īccording to Klein, research does not show whether VE for RZV wanes after 4 years. The CDC currently recommends two doses of RZV separated by 2-6 months for patients aged 50 years and older. 'That's a large number of years to need protection for, so it's really important to have a long-lasting vaccine.' 'People live these days into their 80s and even 90s,' Tien said. The long-term efficacy of the vaccine is especially important because older adults are now living much longer than in previous years, according to Alexandra Tien, MD, a family physician at Medical Associates of Rhode Island in Providence. The findings may quell fears that waiting too long for the second dose reduces the effectiveness of the herpes vaccine, according to Nicola Klein, MD, PhD, director of the Vaccine Study Center at Kaiser Permanente in Oakland, California, who led the study. Researchers evaluated the incidence of HZ, as determined by a diagnosis and prescription for antiviral medication within 7 days of diagnosis, and monitored RZV status over time. The study was conducted between 20 using data from the Vaccine Safety Datalink, a collaboration between the US Centers for Disease Control and Prevention (CDC) and nine healthcare systems across the country. The findings also showed that the rate of effectiveness was 65% for those taking corticosteroids. By contrast, the rate of effectiveness during the first year was 70% for people who received a single dose, falling to 52% effectiveness by year 4. Two doses of the recombinant zoster vaccine (RZV) are effective against herpes zoster (HZ) for 4 years after vaccination, according to a new study published in the Annals of Internal Medicine.įindings from the prospective cohort study showed that people who received two doses of the vaccine, regardless of when they received their second dose, experienced 79% vaccine effectiveness (VE) during the first year, with effectiveness decreasing to 73% by year 4.
