To capture the overall level and growth rate of economic development, we include GDP per Capita (the natural logarithm of GDP per capita) and GDP Growth (the growth rate of GDP) in 2018. Because older people are especially vulnerable to COVID-19, we include the percentage of population ...
However, seroconversion is not the only protective measure because, after a few months, the amount of neutralising antibodies decline56,57 while cellular immunity induced by natural infection plays a significant role in preventing subsequent infections58. On the other hand, vaccination after SARS-CoV-...

Hybrid immunity provides better protection against COVID-19 than vaccination or prior natural infection alone. It induces high magnitude and broadly cross-reactive neutralising anti-Spike IgG antibodies. However, it is not clear how long these potent ant
Patients who recover from COVID-19 make antibodies to the virus that may impart immunity for at least 6 months; however, breakthrough infections do occur and may be more likely with newly circulating variants of the virus. Immunizing with the latest recommended COVID-19 vaccine can help to ...

Such an exit strategy, although controversial, is still considered viable by some countries like Sweden5. Initially, the UK also advocated this approach6, but was heavily...
The most common theme identified was physicians discouraging the public from receiving COVID-19 vaccines. Promoting fear and distrust of the vaccine and reliance on “natural” immunity were common subthemes. Vaccine Ineffectiveness Some of the misinformation propagated by physicians claimed that COVID-...
