A few updates....
Cases may be starting to plateau in the US, Canada and Ireland. This seems to reflect the omicron variant hitting the unvaccinated, including children under the minimum vaccination age and break-through cases in the vaccinated and partially vaccinated.
Australia, which has a >90% vaccination rate, is seeing cases still increasing. About 2/3 of the cases are in the southeastern part of the country where Sydney is located.
Contrast this with Brazil, which was believed to have "herd immunity" because of the unchecked infections in 2020. Brazil also used Sinovac's CoronaVac, which produces a low level of immunity (~50% protection, dropping to ~25% in people over age 80). Brazil started switching to mRNA vaccines in the last quarter of 2021 for their boosters.
At-Home Testing In The US
The US still has a shortage of at-home rapid tests. However, starting next week, you can go to
COVIDtests.gov and request 4 free at-home COVID-19 tests per home address from the federal government.
Also, if you can find home tests,
private insurance policies will start paying for any tests purchased on or after 15-Jan-2022. The maximum number that they will cover is 8 tests per person per month. It's unclear whether insurance companies will ship tests to you on request or whether you will need to submit receipts for reimbursement. Your plan's website should have information.
