The European Union (EU) has drawn up a list of 14 countries whose residents will be allowed to travel to the bloc's member states starting July 1. The countries that figure on the EU's 'safe' list are expected to lift any bans or restrictions that they might have in place on European travellers.
This comes at a time when the European economies are reeling under the impact of the coronavirus and the lockdown that followed. Countries like Greece, Italy and Spain are waiting for travel restrictions to be lifted in order to ease into a resumption of their tourism sectors, which have been hit hard due to the pandemic.Countries on the 'safe' list
The list is to be revised every 14 days, with new countries being added and some even dropping off depending on the extent of the spread of the coronavirus pandemic there and how far these countries are able to control the transmission of the virus.Why US has been left off the list
Frequently Asked Questions
A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.
There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.
Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
