Experts say Canada may find it challenging to reach herd immunity for COVID-19 but a return to pre-pandemic life is possible through vaccinations.
Considered the endgame for a vaccination blitz, herd immunity is achieved when enough people are immune either through vaccinations, infections, or a combination of both.
Professor Paul Tupper from Simon Fraser University s mathematics department says immunity through vaccines and infection doesn t last permanently and because the virus is across the world, COVID is reintroduced in different places across borders.
The virus is being transmitted worldwide, which means it is reintroduced in different places across borders and immunity through vaccination and infection doesn t last permanently. The vaccines don t seem to be completely effective against some of the new variants, he said.

WASHINGTON – The Biden administration on Wednesday joined calls for more sharing of the technology behind COVID-19 vaccines to help speed the end of the pandemic, a shift that puts the U.S. alongside many in the developing world who want rich countries to do more to get doses to the needy.
The Biden administration is throwing its support behind efforts to waive intellectual property protections for COVID-19 vaccines in an effort to speed the end of the pandemic. United States Trade Representative Katherine Tai announced the government s position in a Wednesday statement, amid World Trade Organisation talks over easing global trade rules to enable more countries to produce more of the life-saving vaccines. The administration believes strongly in intellectual property protections, but in service of ending this pandemic, supports the waiver of those protections for COVID-19 vaccines, Tai said in the statement. But she cautioned that it would take time to reach the required global consensus to waive the protections under WTO rules, and US officials said it would not have an immediate effect on the global supply of COVID-19 shots.
