Historic compliance with multi-dose vaccines – Healthcare Economist

It’s not nice. From Nelson et al. (2009):

Amongst those that obtained a primary dose of varicella (n = 16 075), hepatitis A (n = 594 917), and hepatitis B (n = 590 445) vaccine, comparatively few accomplished the sequence (55%–65% for hepatitis B vaccine and 40%–50% for hepatitis A and varicella vaccines in most age teams). Compliance was lowest amongst adolescents (35.9%) and Medicaid recipients (29.7%) who obtained varicella vaccine and amongst youthful grownup age teams who obtained hepatitis A vaccine (25%–35% throughout these age teams). Even amongst sequence completers, there was a comparatively lengthy interval of undervaccination between the primary and final doses.

On the one hand, these vaccinations didn’t have the general public consideration of COVID-19 so maybe compliance can be higher. Particularly, conditional on somebody agreeing to a primary COVID-19 vaccine–which will probably be a particular inhabitants given the (unlucky) politics of the vaccine–maybe second dose compliance can be increased than these noticed in Nelson et al. for different vaccines. Moreover, there may be proof that the COVID-19 vaccines are very efficient even after one dose. Nonetheless, that is some regarding historic precedent within the scientific literature.
