Second Wave on Indian Covid-19 Pandemic Vaccination Strategy Outbreak and Oxygen Crisis with Mathematical Models

The second wave spread on Indian COVID-19 pandemic with vaccination current strategy and Oxygen crisis little bit is identified. We discussed some basic ideas of Mathematical models in COVID-19. We focused Mathematical modeling of COVID-19 in current situation and four COVID-19 model examples are given in this paper. It’s very helpful for mathematical modeling in biology and other researchers for COVID-19.
