We can imagine that the only reason why fewer infants are dying during the lockdown that prior to the lockdown is because they are not going to see the doctor for their routine vaccination schedule.

“As untimely deaths spiked among the elderly in Manhattan nursing homes and in similar settings all over the country, something mysterious was saving the lives of children. As springtime in America came along with massive disruptions in family life amid near universal lockdowns, roughly 30% fewer children died.”
The dramatic decrease in deaths starting in March 2020 when the lock downs began came from infants:
“We have no specific data on the trend in SIDS deaths during the pandemic. We have, however, heard anecdotal reports from emergency room (ER) doctors suggesting some have observed a decline in SIDS. One group of doctors who might see 3 cases of SIDS in a typical week has seen zero cases since the pandemic and associated lockdowns began.
What has changed during this period that might have such an effect? Are infant deaths not being recorded? Are parents taking better care of their families while working remotely and their children are not going to school? There are many possible hypotheses about the infant death decline.
One very clear change that has received publicity is that public health officials are bemoaning the sharp decline in infant vaccinations as parents are not taking their infants into pediatric offices for their regular well‐baby checks. In the May 15 issue of the CDC Morbidity and Mortality Weekly Report (MMWR), a group of authors from the CDC and Kaiser Permanente reported a sharp decline in provider orders for vaccines as well as a decline in pediatric vaccine doses administered.  These declines began in early march, around the time infant deaths began declining.”
If there is any good coming from the lockdowns, this has got to be it.
