Recent findings from an Israeli study indicate that when parents get vaccinated against Covid-19, they not only safeguard their own health but also reduce the risk of infection in their unvaccinated children. While vaccinating eligible children remains the best line of defense against the virus, some kids are unable to receive the vaccine. Fortunately, this study, published in the esteemed Science journal, highlights that having two vaccinated parents significantly diminishes the likelihood of household transmission from adults to their children.
This revelation may not come as a surprise to many, yet experts hope it will motivate some of the 30 million unvaccinated adults in the U.S. to consider getting vaccinated. Dr. Emily Carter, an infectious disease specialist at a major university, remarked, “For those who prioritize their children’s wellbeing, this information could serve as a compelling reason to get vaccinated.”
Study Overview
The research, which involved collaboration between a leading medical school, a prominent university, and a major healthcare organization, focused on households with unvaccinated children under the age of 16 from January to September 2021, prior to the widespread impact of the Omicron variant.
During the initial months of the year, while the Alpha variant was prevalent, the study found that having one vaccinated parent was linked to a 26% reduction in infection risk for children. With two vaccinated parents, the risk dropped dramatically by approximately 72%. Later, when the Delta variant was responsible for many infections, having a vaccinated parent lowered the risk by 21%, and when both parents were boosted, the risk was reduced by 58%.
Moreover, the findings suggested that if a parent contracted the virus, their ability to transmit it to their children was significantly lower if they were vaccinated compared to unvaccinated parents.
Impact on Children’s Health
Earlier research has shown that the health of children during the pandemic is greatly influenced by the indirect effects of vaccination. Vaccinated parents are less likely to introduce the virus into their homes, thereby protecting their children from potential infection. While Covid-19 typically causes milder symptoms in children, there remains a risk of Long Covid and other complications resulting from infection.
Since the CDC endorsed the Pfizer vaccine for children aged 5-11 in December, about 28.1% of kids in this age group have received at least one dose.
