My daughters (no pics) are 26 and 29. They have had every vaccine available as have my wife and I. We are big believers in vaccines. My wife and I (both 58 years old) both have been vaccinated for covid and my 29 year old is in the healthcare biz and she has been vaccinated. My 26 year old gets her first shot on Saturday. But I'm not sure I would give my kids the covid vaccine if they were under 20. Sure, I get the altruistic motive to help with community spread and it's admirable.
Comparing flu deaths in Texas with covid deaths in Texas, for people under 20, the seasonal flu is way more dangerous and we never made our daughters get flu shots in high school or college. For the flu seasons ending the fall of 2016, 2017, 2018, and 2019 the deaths in Texas of persons under 17 is 63, 96, 79 and 82, respectively. For covid, the persons in Texas that died under age 20 is 49. See www.dsha.state.tx.us (for pre-covid flu deaths) and https://txdshs.maps.arcgis.com/apps/opsdashboard/index.html#/ed483ecd702b4298ab01e8b9cafc8b83 for covid deaths. Because the gene therapy-based covid vaccines are relatively new in the vaccine world I'm not sure I would give it to my late teen kids when the disease is not particularly harmful to them. I'm not saying it's foolish to get the shot(s) at that age, but I am saying that it's not crazy to avoid the shot(s) in that age group. It would be a much tougher decision for me if my kids were under 20.
