Childhood immunization during the COVID-19 pandemic in Texas

 In 2020, the state of Texas implemented coronavirus disease 2019 (COVID-19) social distancing guidelines in order to prevent surges at Texas hospital emergency rooms and in intensive care units. As noted in other states, an unintended consequence of these activities was significant declines in childhood immunizations. After analyzing state-wide immunization register data for Texas, we observed a 47% relative decline in immunization rates between 2019 and 2020 among 5-month-olds and a 58% decline among 16-month-olds. We observed a small decline (5%) among 24-month-olds, and no decline in vaccines received at birth (Hepatitis B). Declines were larger in rural counties compared to urban. These declines are superimposed on increases in state vaccine exemptions over the last five years due to an aggressive anti-vaccine movement in Texas. There are concerns that continued declines in childhood immunization coverage due to COVID-19 could lead to co-endemics of measles and other vaccine preventable diseases.

Anti-spikes receptor binding domain (RBD) levels and short-term adverse event dynamics after heterologous booster administration of BNT162b2 after two doses of CoronaVac

CoronaVac was administered in early 2021 as the primary COVID19 vaccine for Thai healthcare professionals (HCWs) in response to a new variant epidemic. The purpose of this study is to evaluate the dynamics of the humoral immune response and the short-term side effects resulting from the additional administration of BNT162b2 after the completion of two doses of CoronaVac in Thai healthcare professionals. This study was conducted in August and September 2021 at a teaching hospital in northern Thailand. Participants were 50 healthcare workers vaccinated with two doses of CoronaVac and were expected to receive an additional dose of BNT162b2. We evaluated AntiSARSCoV2 IgG antibody levels and short-term side effects. Anti-RBD levels were determined using Architect SARSCoV2 IgG II Quant (Abbott). Of the 50 participants, 37 were women. The average age was 33.0 years. The average time between the second CoronaVac vaccination and the BNT162b2 booster was 81.7 days (SD = 25.0). Median anti-SARSCo

Vaccines and immunization: Vaccine safety

Image
Vaccination is one of the best ways to prevent illness. Overall, the vaccine is estimated to save 2 to 3 million lives each year. Together with the government, vaccine manufacturers, scientists, and medical professionals, the WHO Vaccine Safety Program continues to support vaccine safety monitoring. This helps ensure that the vaccine is safe for you and your family. The most commonly used vaccines today have been in use for decades, with millions of people safely receiving the vaccine each year. Several new vaccines are also under development. Once approved, they should help prevent other life-threatening illnesses such as Zika virus and Nipah virus, and improve the effectiveness of existing vaccines. Like all medicines, all vaccines must undergo extensive and rigorous testing before being introduced into the country. After use, it should be continuously monitored to ensure it is safe for the people who receive it. Vaccines are very safe. As with all medicines, side effects can occur
