The second wave of COVID_19 cases will end up costing more in the long term,it now clear that many countries have failed to take thorough enough measures to combat this pandemic ,or have utilized short _sighted plans at the expense of long-term case reductions . Even after delivery of a vaccine I think it takes longer time than the expected.
Dear Mohammed Ismael Rushdi in our country, Germany, the second wave of the corona pandemic is in full swing and there is no end in sight. Please see this recent link entitled "Covid-19: Is Germany losing the fight against the second wave?" https://www.newscientist.com/article/2258845-covid-19-is-germany-losing-the-fight-against-the-second-wave/
It is somewhat frightening to see in the attached diagram that the second wave of COVID-19 is much higher than the first one!
There are some questions puzzling me: Does anyone know how long the protection by a COVID-19 vaccination will last? Will we need to get vaccinated again after one or two years? If yes, must it be the vaccine from the same company or can it be different?
Very recent studies have revealed that the BioNTech-Pfizer vaccine is also effective against the new coronavirus strain. Please see the very recent link entitled "Pfizer vaccine appears to neutralize a key mutation of Covid variants found in UK, South Africa"
