Nearly a dozen countries in Europe, including Spain, France, Germany, Italy, Denmark, Norway, and Sweden, have halted the use of AstraZeneca COVID-19 vaccine shots amid concerns over possible serious side-effects. AstraZeneca and medical experts in Britain have said there is no evidence of blood clots being caused by the jab. Britain's Foreign Secretary Dominic Raab on Tuesday came to the vaccine's defense saying it's safe, and added there's no reason to pause its rollout.
