In June 2013, Novavax acquired the Matrix-M adjuvant platform with the purchase of Swedish company Isconova AB and renamed its new subsidiary Novavax AB.{{cite news|last1=Taylor|first1=Nick Paul|title=Novavax makes $30M bid for adjuvant business|url=http://www.fiercepharma.com/vaccines/novavax-makes-30m-bid-for-adjuvant-business|access-date=9 September 2016|work=FiercePharma|date=3 June 2013|archive-date=14 September 2016|archive-url=https://web.archive.org/web/20160914235336/http://www.fiercepharma.com/vaccines/novavax-makes-30m-bid-for-adjuvant-business|url-status=live}}

In March 2015, the company completed a Phase I trial for its Ebola vaccine candidate,{{Cite news|url=https://www.reuters.com/article/us-health-ebola-novavax-idUSKCN0PV1V720150721|title=Novavax's Ebola vaccine shows promise in early-stage trial|date=21 July 2017|work=Reuters|access-date=28 March 2017|archive-date=2 October 2016|archive-url=https://web.archive.org/web/20161002130324/http://www.reuters.com/article/us-health-ebola-novavax-idUSKCN0PV1V720150721|url-status=live}} as well as a phase II study in adults for its respiratory syncytial virus vaccine, which would become ResVax.{{Cite web|url=http://www.fiercebiotech.com/biotech/novavax-craters-after-phase-iii-rsv-f-vaccine-failure-seeks-path-forward|title=Novavax craters after Phase III RSV F vaccine failure; seeks path forward|last=Adams|first=Ben|date=16 September 2016|website=FierceBiotech|publisher=Questex|url-status=live|archive-url=https://web.archive.org/web/20200818074115/https://www.fiercebiotech.com/biotech/novavax-craters-after-phase-iii-rsv-f-vaccine-failure-seeks-path-forward|archive-date=18 August 2020|access-date=25 January 2020}} The ResVax trial was encouraging as it showed significant efficacy against respiratory syncytial virus (RSV) infection, using a nanoparticle-based treatment using a recombinant F lipoprotein or saponin, "extracted from the Quillaja saponaria [or?] Molina bark together with cholesterol and phospholipid."{{cite web |title=Novavax addresses urgent global public health needs with innovative technology |url=https://novavax.com/our-unique-technology |website=novavax.com |access-date=30 August 2020 |archive-date=10 September 2020 |archive-url=https://web.archive.org/web/20200910142543/https://novavax.com/our-unique-technology |url-status=live }} It is aimed at stimulating resistance to RSV infection, targeting both adult and infant populations.

2016 saw the company's first phase III trial, the 12,000 adult Resolve trial, for its RSV vaccine, which would come to be known as ResVax, fail in September.{{Cite news|url=http://www.biopharmadive.com/news/Novavax-q3-restructure-RSV/430370/|title=Novavax aims to rebound with restructuring, more trials|last=Bell|first=Jacob|date=14 November 2016|work=BioPharma Dive|access-date=28 March 2017|url-status=live|publisher=Industry Dive|location=Washington, D.C.|archive-date=29 March 2017|archive-url=https://web.archive.org/web/20170329140758/http://www.biopharmadive.com/news/Novavax-q3-restructure-RSV/430370/}} This triggered an eighty-five percent dive in the company's stock price. Phase II adult trial results also released in 2016 showed a stimulation of antigenicity, but failure in efficacy. Evaluation of these results suggested that an alternative dosing strategy might lead to success, leading to plans to run new phase II trials. The company's difficulties in 2016 led to a three-part strategy for 2017: cost reduction through restructuring and the termination of 30% of their workforce; pouring more effort into getting ResVax to market; and beginning clinical trials on a Zika virus vaccine.

Alongside the adult studies of ResVax, the vaccine was also in 2016 being tested against infant RSV infection through the route of maternal immunization.

In 2019, late-stage clinical testing of ResVax failed for a second time, which resulted in a major downturn in investor confidence and a seventy percent reduction in capital value for the firm.{{Cite web|url=https://www.nasdaq.com/articles/3-biotech-stocks-that-offer-the-highest-upside-on-wall-street-2019-12-12|title=3 Biotech Stocks That Offer the Highest Upside on Wall Street|last=Shtrubel|first=Marty|date=12 December 2019|website=Biotech|publisher=Nasdaq|url-status=live|archive-url=https://web.archive.org/web/20200126014804/https://www.nasdaq.com/articles/3-biotech-stocks-that-offer-the-highest-upside-on-wall-street-2019-12-12|archive-date=26 January 2020|access-date=25 January 2020}}{{Cite web|url=https://www.nasdaq.com/articles/3-top-biotech-picks-for-2020-2020-01-20|title=3 Top Biotech Picks for 2020|last=Budwell|first=George|date=20 January 2020|website=Markets|publisher=Nasdaq|at=Novavax: A catalyst awaits|url-status=live|archive-url=https://web.archive.org/web/20200125233600/https://www.nasdaq.com/articles/3-top-biotech-picks-for-2020-2020-01-20|archive-date=25 January 2020|access-date=25 January 2020}} As a secondary result, the company was forced to conduct a reverse stock split in order to maintain Nasdaq minimum qualification, meaning it was in risk of being delisted.

On 22 December 2021, Novavax confirmed the efficacy of two doses of vaccine against the omicron variant of SARS-CoV-2. The new data suggest that the vaccine provides an immune response against the Omicron variant and other variants of the coronavirus. The response of antibodies against omicron is four times lower than the original variant. A third dose of the vaccine given to adults, six months after the first two doses, increased the level of neutralizing antibodies against the omicron variant by 73.5 times, making it more effective in preventing omicron from entering human cells.
