POLIO & OTHER CHILDHOOD VACCINES: Polls show that public health lost trust during the COVID pandemic by not emphasizing #harmreduction enough (minimize pathogen's effects within needs of society). PH must work on trust; but childhood vaccines like polio essential- please, parents

How can you go from sequence of a novel virus to 2 vaccines with 95% efficacy and safety (>75,000 participants in RCT trials) in 10 months and not, in 2.5 years, go after pan-β-coronavirus and nasal vaccines with the same aggressive (OWS) template?
rarely does one event expose the emptiness of a political party's arguments as clearly as Uvalde has exposed Republican arguments against action on guns
An emergency doctor and parent sorts through Covid vaccine options for kids under 5 statnews.com/2022/05/27/jer… via @statnews
As we listen to the debate tonight, the alternatives become very clear: Either we can have gunmen roaming free and the children locked up like jailed felons ... Or we can impose some restrictions on the guns and let the children enjoy the air and sun Your values. Your choice.
A society that allows its children to be murdered at school has failed its children. But we can and must change.
Enough is enough. As a nation, we must have the courage to take action and prevent this from ever happening again. It is long past time for our country to stand up to the gun lobby and pass reasonable gun safety laws.
14 children and a teacher dead. Another shooting. And the GOP won’t do a damn thing about it. Who the hell are we if we cannot keep our kids safe. This is preventable. Our inaction is a choice. We need nationwide, comprehensive, commonsense gun safety NOW.
Thoughts and prayers are not enough. After years of nothing else, we are becoming a nation of anguished screams. We simply need legislators willing to stop the scourge of gun violence in America that is murdering our children.
