Finding is good news for lower-income countries that have not yet completed their primary vaccination campaigns
Combining a first dose of the AstraZeneca Covid-19 vaccine with a second dose of either the Moderna or the Novavax jabs results in far higher levels of neutralising antibodies and T-cells compared with two doses of the AstraZeneca jab, a study has found.
The finding has important implications for lower-income countries that have not yet completed their primary vaccination campaigns, as it suggests you do not need access to mRNA vaccines – and therefore ultra-cold storage facilities – to trigger an extremely potent Covid-19 vaccine response.
