Does it matter at what age a child experienced the COVID shock for subsequent learning?

At 23.8GW it meant that even during winter peak demand, it was still providing nearly half the country's power needs

Further evidence that widespread covid vaccination is better for everybody.
A study on 1.7 million people in Hong Kong shows superior hybrid immunity to Covid in people who got vaccinated before infection vs. people who got infected first. "Our findings are a direct rebuttal to arguments for natural immunity," the authors write. doi.org/10.1016/j.va...
