A day after Russia announced it had approved a COVID-19 vaccine, it was defending the speed at which it was developed, saying it was in the works for the last six years. New Zealand reported four new positive cases of coronavirus after 102 days of no confirmed cases and decided to lock Auckland back down.

Elsewhere, New Jersey Gov. Phill Murphy did an about-face and said schools can teach remotely starting in the fall if they want to.

The response from Russia comes after critics wondered how safe and effective a COVID-19 vaccine could be when developed in less than two months. While no data has been released, Russia said it plans to deliver the vaccine to the public by the end of 2020, CNBC reported.

“Western colleagues, who can sense the competitive advantage of the Russian drug, are trying to express some opinions that are completely unjustified in our view,” Health Minister Mikhail Murashko told a briefing Wednesday. “This vaccine is a platform that is already well-known and studied.”

The Russian Direct Investment Fund said it has application requests from 20 countries for more than 1 billion doses of the vaccine, which is expected to begin inoculations later this month before phase 3 clinical trials are completed.

Russia said it has been developing the vaccine for the last six years, drawing from the work it has done to develop a vaccine for Ebola and Middle East Respiratory Syndrome, but the World Health Organization said there is not an approved vaccine to treat MERS currently available and the U.S. Food and Drug Administration only approved an Ebola vaccine in December.

“We were just fortunate that the coronavirus was very close to MERS, so we pretty much had a ready-to-go vaccine on MERS, studied for two years on MERS [and] slightly modified to be the coronavirus vaccine, and that is the real story, no politics. ... Russia has always been at the forefront of vaccine research,” Kirill Dmitriev, CEO of the direct investment fund, told CNBC.

In New Zealand, Auckland was locked down after the country saw four new positive cases of the coronavirus after a record 102 days without a single confirmed case. New Zealand has had more than 1,500 confirmed cases of the coronavirus and 22 COVID-19 deaths, data from Johns Hopkins University showed.

Four members of a family in Auckland, the largest city in New Zealand, tested positive for the coronavirus on Tuesday, prompting officials to lock down the city in a Level 3 restriction, meaning all businesses, schools, public facilities, and restaurants and bars were closed. Residents are also encouraged to stay home and wear a face mask in public.

It is suspected a family member, an employee of the U.S. cold storage transportation firm Americold Realty Trust, contracted the virus from freight and passed it on to three other family members.

“As we have seen in other countries where a resurgence occurs, it’s incredibly important to act early,” Director General of Health Ashley Bloomfield told reporters. “We have done this before and we can do it again.”

An investigation into the source of the coronavirus is ongoing with surface testing being conducted to avoid further spread of the virus in New Zealand.

Also, New Jersey, Gov. Phill Murphy reversed his stance on school reopenings, allowing nearly 600 school districts in the state to make the decision whether to hold in-person classes or teach remotely.

The announcement from Murphy is a departure from his previous insistence that New Jersey schools should reopen with in-person classroom teaching in the fall. Murphy said during a news briefing schools that cannot meet health and safety standards set by the New Jersey Department of Education can choose to hold remote classes.
