Around the world, from Italy to Québec, authorities are using everything from mandates to incentives to try to get people vaccinated. Here’s why mandates aren’t always effective, are difficult to enforce and often lead to protests like the one seen here in Rome. (AP Photo/Andrew Medichini)

Carrots, sermons, sticks: Vaccine mandates face opposition around the globe

Having exhausted policy tools to convince vaccination holdouts to change their minds, it seems little can be gained from additional vaccine mandates than further weakening social cohesion.

‘Never’ or just ‘not yet?’ How timing affects COVID-19 vaccine hesitancy

Vaccine hesitancy may be a waiting game. Even those who said they would never get the COVID-19 vaccine if it were available immediately became more likely to do so when it was available in the future.

COVID-19 vaccine mandates would likely face legal hurdles in Canada

Can the government mandate vaccines? Canadians have rights to make decisions about vaccination, but these rights are not absolute, and do not mean those decisions will have no consequences.

Omicron: Vaccines remain the best defence against this COVID-19 variant and others

Even with a variant like Omicron that may be more transmissible than earlier variants, vaccines remain the most effective tool for protection against COVID-19 and for ending the pandemic.
It can be difficult to distinguish between the calls of sincere scientists for more research to reach greater certainty, and the politically motivated criticisms of science skeptics. (Shutterstock)

Scientific certainty survival kit: How to push back against skeptics who exploit uncertainty for political gain

Skeptics may make demands for absolute certainty to undermine science and delay action. Critiques may not be in the interest of advancing science and public health, but by someone with an agenda.

The nanoparticles in mRNA vaccines are nothing to fear: We interact with many useful, tiny particles every day

Some vaccine hesitancy is based on a fear of the nanoparticles used in mRNA vaccines. But humans have been interacting with nanoparticles for millennia, and we use nanotechnology-based devices every day.
