Context: Clay gets up from his trailer at the beach and drives to Mr. Jimmy's lush house, where he mows the lawn.Mr. Jimmy has a visit from David, who is concerned about his health. He then goes out to chat with Clay, his new gardener, and invites him to swim in the pool after he is done working. Clay says he needs to do another lawn later.An academic named Edmund Kay comes to visit Mr. Jimmy, and expresses his deep enthusiasm for his films. Jimmy takes him out back to the pool, and recalls his youth in London, and then his movement into movies and on to Hollywood.Mr. Jimmy becomes bored with Kay's questions, and suggests that Kay begin removing clothing in exchange for his answers. Kay begins disrobing to each of Jimmy's tales about homosexuals in Hollywood and making Frankenstein.Jimmy then gets lightheaded and needs Kay's help to get inside and lie down. His maid Hanna scolds him for chasing boys after just returning from the hospital.Jimmy goes to a doctor who explains that he had a stroke which has left his brain somewhat impaired.Jimmy sees Clay working out in the garden and invites him to talk over iced tea in his painting studio. Jimmy tells him he directed the first two Frankenstein movies, and they talk about his paintings. Jimmy tells Clay he has an expressive head and asks him to model for pay; Clay agrees.Clay arrives at Jimmy's house and Hanna asks if he is going to hurt him. Clay is confused, and she withdraws the question. Clay sits down in the studio to model for Jimmy, who asks him to remove his shirt, even though he only plans to draw his face. Jimmy begins to draw, telling Clay of a memory he has about eating fat drippings as a poor child. He explains how different he was from his family, more talented, more intelligent.Clay goes to a bar and boasts that a famous director is drawing him. Betty the bartender, whom Clay has slept with, turns on The Bride of Frankenstein on TV; meanwhile, Jimmy watches at home with Hanna. The others at the bar criticize the film for not being scary. Clay seems to understand the monster's feelings of loneliness.Flashback: Jimmy directs the performers on the set of Bride of Frankenstein.Clay and Betty talk outside the bar, and he gets upset that she does not want to sleep with him again.Clay calls his parents from a payphone but does not want to talk much.Jimmy dreams that Clay is Dr. Frankenstein, replacing his brain and electrifying him.Hanna tells Clay that Jimmy would like him to have lunch. The two talk as she cooks, and Hanna tells him he should be married. Hanna tells Clay that Jimmy commits unspeakable sins of the flesh, buggery. She is surprised that Clay did not know.Jimmy and Clay have a rather fancy lunch. Jimmy tells Clay that he had hoped Bride of Frankenstein would be seen as a comedy. Jimmy asks Clay to pose for an hour after lunch, and he declines. Jimmy explains that he had a "husband" named David, and Clay asks about his homosexuality. They smoke cigars, and Clay agrees to pose.During the sitting, Jimmy talks about how he made the successful Show Boat and then tried to make his WWI masterpiece The Road Back but the studio butchered it. He says he always wanted to go back to movies, but that was the end. He also broke up with David thereafter. Jimmy begins to describe how he used to have many male models, all naked, which upsets Clay so much he gets mad and storms out.Clay goes to Betty's bar but she is not there. He finds another woman and has sex with her in the parking lot.Clay returns to Jimmy's house and says he will sit for him again if he eases up on the locker room talk. Jimmy is curious that Clay has never known any gay men before, not even when he was in the Marines. Jimmy recalls a young soldier from WWI he mentored in the trenches, then becomes quite upset, looking at Clay intensely

Context: The circumsporozoite protein (CS protein) on the malaria parasites in mosquitoes plays an important role in sporogony in mosquitoes. The RTS,S/AS01 malaria vaccine candidate, which has shown significant efficacy against clinical malaria in a large Phase 3 trial, targets the Plasmodium falciparum CS protein, but the ability of serum from vaccinated individuals to inhibit sporogony in mosquitoes has not been evaluated. Previously a double-blind, randomized trial of RTS,S/AS01 vaccine, as compared with rabies vaccine, in five- to 17-month old children in Tanzania was conducted. In this study, polyclonal human antibodies were purified from the pools of sera taken one month after the third vaccination. IgGs were purified from four pools of sera from 25 RTS,S/AS01 vaccinated children each, and two pools of sera from 25 children vaccinated with rabies vaccine each. The ability of antibodies to inhibit P. falciparum oocyst formation and/or sporogony in the mosquito host was evaluated by a standard membrane-feeding assay. The test antibodies were fed on day 0 (at the same time as the gametocyte feed), or on days 3 or 6 (serial-feed experiments). The oocyst and sporozoite counts were performed on days 8 and 16, respectively. In addition, two human anti-CS monoclonal antibodies (mAb) and a control mAb were also evaluated. Polyclonal anti-CS IgG preparations from RTS,S-vaccinated children tested at concentrations of 149-210 ELISA units (EU)/ml did not show significant inhibition in oocyst and sporozoite formation when the antibodies were fed with gametocytes at the same time, or later (serial-feed experiments). Similarly, anti-CS mAbs tested at 6,421 or 7,122 EU/ml did not show reduction in oocyst and sporozoite formation. This study does not support the concept that anti-CS antibodies induced by the RTS,S/AS01 vaccines in humans noticeably reduce malaria transmission by blocking P. falciparum sporozoite development or salivary gland invasion in mosquitoes when taken up during feeding. 
 Question: RTS S AS01 vaccine was developed to prevent which disease?

Ex Output:

malaria
