Covid-19: When will we reach herd immunity? Here are 3 reasons that's a hard question to answer

Different diseases have different thresholds for herd immunity. For measles, for example, the herd immunity threshold is 92%-94%. Estimates for COVID-19 have varied, with some putting it at 85% or higher. However, many hesitate to give a single number. Here are three reasons why.

This time last year, the Bill and Melinda Gates Foundation warned of a grim potential side effect from the COVID-19 pandemic: its disruptions to routine medical care could erase 25 years of progress on childhood vaccination, setting back global health by decades. The 2021 installment of the foundation’s annual Goalkeepers report, which details progress on 18 metrics related to global health, equity and sustainability, contains some good news and some bad news. Childhood vaccination rates have suffered during the pandemic—but only about half as much as the Gates Foundation originally predicted, signaling that ma...

MMWR Morb Mortal Wkly Rep. 2021 Sep 3;70(35):1183-1190. doi: 10.15585/mmwr.mm7035a1.ABSTRACTThe Advisory Committee on Immunization Practices (ACIP) recommends that adolescents aged 11-12 years routinely receive tetanus, diphtheria, and acellular pertussis (Tdap); meningococcal conjugate (MenACWY); and human papillomavirus (HPV) vaccines. Catch-up vaccination is recommended for hepatitis B (HepB); hepatitis A (HepA); measles, mumps, and rubella (MMR); and varicella (VAR) vaccines for adolescents whose childhood vaccinations are not current. Adolescents are also recommended to receive a booster dose of MenACWY vaccine at age...

In March, when President Biden announced that COVID-19 vaccines would soon be available to all Americans, my husband and I decided to press pause on the whole maybe-getting-pregnant-soon thing. We would get our vaccines first, have a Hot Vaxxed Summer full of booze and parties, and then go back to the kids question once we had shaken off the COVID cobwebs. Lucky for us, it was too late: it turned out I was already pregnant. I was thrilled, but also anxious. I had been all-in on getting the vaccine; getting it while pregnant was a different story. At the time, the CDC had not yet issued a full-throated recommendation that ...

CONCLUSION: The ongoing COVID-19 epidemic may lead to health consequences other than those directly attributable to the disease itself. Specifically, lockdowns and foregoing healthcare could be very harmful at the individual and population levels. The latter issue is a concern for French public authorities, which have implemented actions aimed at encouraging patients to immediately seek treatment. However, the COVID-19 crisis has also created opportunities, such as the roll-out of teleconsultation and tele-expertise. The indicators described here as part of the monitoring system can help public decision-makers to become mo...

Results showed that the first cases of COVID-19 in the human population appeared in the period between July and November 2019 in China. The spread of the virus into other countries of the world began in the autumn of 2019. In mid-February 2020, the...
