Hawaii and Puerto Rico are tropic areas of USA. These two areas like sensors of USA upon summer effects on COVID-19 PANDEMIC. Puerto Rico new infection peaked on April 10 with 110 infections, yesterday down to 50. For April 13 to April 18, total 200 new infections, or average 40 new infections/day. Hawaii new infection peaked on March 31 with 30 infections, and now 21 new cases in April 18. For the past week, total new infections were 95. Therefore, USA tropic zone leads the way of ending COVID-19 Pandemic this summer.

From the standing point of COVID-19 vaccine, for anti-COVID-19 IgG has been used as diagnosis tools, with more than 90% been positive for anti-COVID-19 IgM/IgG post infection, inactive vaccines certainly would be an effective vaccine.
