Viruses were found to interact with newborns' immune systems and microbiomes — the community of microbes that live in our body — in a way that affected both a child's risk and number of subsequent infections.
Prevention of such early viral infections, or strengthening immune systems with specially designed probiotics, may avert this risk, experts say.
The microbiome of a newborn baby can be influenced by many things, including delivery method — vaginal or cesarean section — breastfeeding, antibiotics and the hospital environment.
Comment: Rather than 'preventing early viral infections' or intervention with 'specially designed probiotics', research is increasingly showing that improving the overall health of the mother, delivering the baby vaginally, and breastfeeding, all directly contribute to the improved health of the baby. It's also likely that improving the health of the father before and after conception will have similar effects.
Comment: The claim that the best course of action would be to limit exposure to viruses seems to contradict many of the findings that gained recognition during the lockdowns. These showed that allowing the circulation of a virus can in fact reduce its harmful effects both in priming and strengthening one's immune system, as well the effect they have in forcing the virus to mutate which tends to result in milder strains.
Lockdowns also proved that limited human interaction, prolonged and heightened periods of stress, inadequate nutrition, sunlight and fresh air, only serve to make people more vulnerable to the harm caused by some viruses:
