Profile of SARS-CoV-2	2020-10-30		.txt	text/plain	6028	301	44	Despite these similarities, distinguishing features were identified that are likely to contribute to the biological differences observed between the two viruses, including the significantly higher rate of subclinical and mild infections caused by SARS-CoV-2, which makes control of virus spread currently so difficult. If expectations were too optimistic and results obtained with some of the front runners are disappointing, windows of opportunity will open for an arsenal of alternative developments in progress [54, 59] (https:// www.who.int/publications/m/item/draft-landscapeof-covid-19-candidate-vaccines, accessed 2 October 2020) These include subunit vaccines with S proteins stabilized in their prefusion conformation in combination with potent adjuvants, use of the RBD only as an immunogen instead of the whole S protein [67, 68] , other rationally designed immunogens [69] , other (non-Adeno) vector vaccines including replication-competent vectors [55, 70] , self-amplifying RNA vaccines [71] , live-attenuated vaccines [55] , DNA vaccines [72] , and intranasally applied vaccines with the potential to induce local immunity at the site of virus entry [73] .	./cache/cord-337712-ylqgraos.txt	./txt/cord-337712-ylqgraos.txt
